A position in infinite chess with game value $ω^{4}$

C. D. A. Evans, Joel David Hamkins, Norman Lewis Perlmutter

We present a position in infinite chess exhibiting an ordinal game value of $ω^{4}$ , thereby improving on the previously largest-known values of $ω^{3}$ and $ω^{3} \cdot 4$ .

Transfinite game values in infinite chess

C. D. A. Evans, Joel David Hamkins

We investigate the transfinite game values arising in infinite chess, providing both upper and lower bounds on the supremum of these values---the omega one of chess---with two sens…
