Taylor, Buck give Leicestershire the edge
Leicestershire 269 and 12 for 0 lead Gloucestershire 260 (Jones 93, W Gidman 52, Taylor 5-55, Buck 4-81) by 21 runs
Will Gidman added a half-century to his five-wicket haul and Geraint Jones rolled back the years with a brutal 93 for Gloucestershire, but it was Leicestershire who marginally held the edge after day two at Grace Road.
Gidman followed up his 5 for 56 on Monday with an unbeaten 52 while former England wicketkeeper Jones fell just short of a blistering century to lead their side's reply to Leicestershire's 269. But their efforts were not enough to earn Gloucestershire a first-innings lead as a late collapse saw them dismissed for 260 as Rob Taylor and Nathan Buck shared nine wickets.
Leicestershire then reached 12 without loss in their second innings, for an overall lead of 21, before bad light and then rain brought an early end to proceedings.
The home side, looking for their first County Championship win since 2012, made good progress during the morning session to reduce the visitors to 94 for 4 at lunch - having started the day 12 for 0.
Chris Dent and Hamish Marshall both fell to Buck while Taylor accounted for Alex Gidman for 18 and the dangerous Michael Klinger for 37 to leave Leicestershire firmly in the box seat at the interval. But Jones and Will Gidman then led a Gloucestershire fightback in the afternoon with a fifth-wicket stand worth 107.
The 37-year-old Jones, who recently joined on loan from Kent, led the charge as he struck 13 fours and three sixes off 75 balls before his onslaught was brought to an end by Jigar Naik, trapped lbw.
While Jones and Will Gidman were together Gloucestershire looked capable of claiming a sizeable lead, but once that stand was broken the end was not long in coming for the visitors as they lost their last six wickets for just 65 runs.
Only Will Gidman stood firm, finishing unbeaten off 123 balls with seven fours, as Taylor - with his second five-wicket haul in first-class cricket - and one-time England Lions seamer Buck ran through the tail.
Greg Smith, who was out for a golden duck in the first innings, and Angus Robson then saw the hosts through to the close.
