  the	training	of	the	German	IMO	team	from	a	timewhen	we	had	only	a	short	training	time	of	14	days,	including	6	half-day	tests.	Thishas	forced	upon	us	a	training	of	enormous	compactness.	Great	Ideas	were	theleading	principles.	A	huge	number	of	problems	were	selected	to	illustrate	theseprinciples.	Not	only	topics	but	also	ideas	were	efficient	means
  of	classification.For	whom	is	this	book	written?	For	trainers	and	participants	of	contests	of	all	kinds	up	to	the	highest	level	ofinternational	competitions,	including	the	IMO	and	the	PutnamCompetition.	For	the	regular	high	school	teacher,	who	is	conducting	a	mathematics	cluband	is	looking	for	ideas	and	problems	for	his/her	club.	Here,	he/she	will
  findproblems	of	any	level	from	very	simple	ones	to	the	most	difficult	problemsever	proposed	at	any	competition.	For	high	school	teachers	who	want	to	pose	the	problem	of	the	week,	problemof	themonth,	and	research	problems	of	the	year.This	is	not	so	easy.Many	fail,but	some	persevere,	and	after	a	while	they	succeed	and	generate	a
  creativeatmosphere	with	continuous	discussions	of	mathematical	problems.	For	the	regular	high	school	teacher,	who	is	just	looking	for	ideas	to	enrichhis/her	teaching	by	some	interesting	nonroutine	problems.	For	all	those	who	are	interested	in	solving	tough	and	interesting	problems.The	book	is	organized	into	chapters.	Each	chapter	starts	with
  typical	examplesillustrating	the	main	ideas	followed	by	many	problems	and	their	solutions.	Thevi	Prefacesolutions	are	sometimes	just	hints,	giving	away	the	main	idea	leading	to	the	solu-tion.	In	this	way,	it	was	possible	to	increase	the	number	of	examples	and	problemsto	over	1300.	The	reader	can	increase	the	effectiveness	of	the	book	even	more
  bytrying	to	solve	the	examples.The	problems	are	almost	exclusively	competition	problems	from	all	over	theworld.	Most	of	them	are	from	the	former	USSR,	some	from	Hungary,	and	somefrom	Western	countries,	especially	from	the	German	National	Competition.	Thecompetition	problems	are	usually	variations	of	problems	from	journals	with	prob-lem
  sections.	So	it	is	not	always	easy	to	give	credit	to	the	originators	of	the	problem.If	you	see	a	beautiful	problem,	you	first	wonder	at	the	creativity	of	the	problemproposer.	Later	you	discover	the	result	in	an	earlier	source.	For	this	reason,	thereferences	to	competitions	are	somewhat	sporadic.	Usually	no	source	is	given	if	Ihave	known	the	problem	for
  more	than	25	years.	Anyway,	most	of	the	problemsare	results	that	are	known	to	experts	in	the	respective	fields.There	is	a	huge	literature	of	mathematical	problems.	But,	as	a	trainer,	I	knowthat	there	can	never	be	enough	problems.	You	are	always	in	desperate	need	of	newproblems	or	old	problems	with	new	solutions.	Any	new	problem	book	has
  somenew	problems,	and	a	big	book,	as	this	one,	usually	has	quite	a	few	problems	thatare	new	to	the	reader.The	problems	are	arranged	in	no	particular	order,	and	especially	not	in	increasingorder	of	difficulty.We	do	not	knowhow	to	rate	a	problems	difficulty.	Even	the	IMOjury,	now	consisting	of	75	highly	skilled	problem	solvers,	commits	grave
  errorsin	rating	the	difficulty	of	the	problems	it	selects.	The	over	400	IMO	contestantsare	also	an	unreliable	guide.	Too	much	depends	on	the	previous	training	by	anever-changing	set	of	hundreds	of	trainers.	A	problem	changes	from	impossible	totrivial	if	a	related	problem	was	solved	in	training.I	would	like	to	thank	Dr.	Manfred	Grathwohl	for	his	help
  in	implementingvarious	LaTEX	versions	on	the	workstation	at	the	institute	and	on	my	PC	at	home.When	difficulties	arose,	he	was	a	competent	and	friendly	advisor.There	will	be	some	errors	in	the	proofs,	for	which	I	take	full	responsibility,since	none	of	my	colleagues	has	read	the	manuscript	before.	Readers	will	missimportant	strategies.	So	do	I,	but	I
  have	set	myself	a	limit	to	the	size	of	the	book.Especially,	advanced	methods	are	missing.	Still,	it	is	probably	the	most	completetraining	book	on	the	market.	The	gravest	gap	is	the	absence	of	new	topics	likeprobability	and	algorithmics	to	counter	the	conservative	mood	of	the	IMO	jury.One	exception	is	Chapter	13	on	games,	a	topic	almost	nonexistent	in
