Each round both fighters secretly pick a move and it resolves once both have: strike beats grapple, grapple beats block, block beats strike; dodge beats strike and grapple but costs the most stamina; rest costs nothing and regains stamina but takes full damage if attacked. Two strikes or two grapples hit both fighters. Moves cost stamina (legal_moves only lists what you can afford). HP 30, stamina 30, 40 rounds max; a KO or higher HP wins the fight. A match is several fights.","turn_seconds":60}
