The 2015 World Series of Poker Main Event kicked off yesterday with a Day 1a starting flight of 741 entries. The number was down slightly from the 771 entries on Day 1a of the 2014 WSOP Main Event, but by all accounts it keeps the 6,683 total number of entries from last year well within reach.

By the time five two-hour levels of play were through, just 480 players remained with 2015 WSOP Event #11: $1,500 Limit Hold'em bracelet winner William Kakon holding the chip lead on 153,325. Kakon has booked four cashes at the 2015 WSOP so far, worth close to $240,000.

The 2015 WSOP Main Event will continue with Day 1b starting at 12 p.m. local time. Another five two-hour levels are on the schedule, and plenty of top players will be in the mix. Those who survived Day 1a will be back to play Day 2a at 12 p.m. local time Wednesday July 8.

Last year, Day 1b attracted 2,144 numbers.
