2. 1. 2 n-in-a-row As promised in the first section, let us use the Erd˝os-Selfridge Criterion to prove that there is some n, such that the n-in-a-row strong game played on the infinite integer grid Z2 is a draw. Recall that it is widely believed that the statement should already be true for n = 6. The following simple method works for n = 40 and proves that the game is not only a draw, but a Strong Draw. 3. The 40-in-a-row game on the infinite board is a Strong Draw. Proof. ([10]) SP (or rather Breaker) partitions the infinite board into 40 × 40 squares in the canonical way and plays an individual game on each of these finite boards, always answering in the 40 × 40 square of the partition where Maker played his previous move.

Indeed, by the proposed strategy (with the possible exception of the last time), whenever Maker claims an edge which is incident to a vertex x, Breaker claims at least b/2 edges which are incident to x. It follows that Maker’s degree n−1 at x is at most 1 + b/2 +1 ≤ b/2 + 1. The same argument applies to any vertex of Kn and thus to the maximum degree in Maker’s graph. Suppose, to the contrary, that Maker wins the game. Let u, v, w be vertices of Kn such that uv, vw and uw were all claimed by Maker; assume without loss of generality they were claimed in this order.

An ). 4. 1 yields the sufficient condition n −ai /p < 1/2. 3 is stronger than the i=1 2 standard criteria one obtains for a general Maker-Breaker game. 3. At any point during the game a box is called surviving if it was not previously destroyed by BoxBreaker; we denote the set of surviving boxes by S. At any point during the game the size of a box is the number of balls it still contains. Again, BoxBreaker employs the obvious strategy: in every move he destroys a box i whose size is minimal among the set S of all surviving boxes (breaking ties arbitrarily).
